40 years of sales partnership in Argentina “Trust, innovation, and close friend,” said Juan Cáceres Diaz, PEMA Sales partner in Argentina since 1980, when asked to describe the cooperation with Pemamek. Cáceres Diaz knows Pemamek and its products well as he has been boosting PEMA sales on the west coast of the Atlantic ocean already for 40 years. The work has paid off resulting in a strong presence in the area. Currently, there’s a big number of PEMA positioners and roller beds, as well as welding column & booms and assembly stations for tubular structures, in Argentina.

“Everyone in Argentina knows Pemamek and the PEMA brand. There is no other company that has the same level of technology as Pemamek. PEMA welding automation technology is number 1 in the world,” said Cáceres Diaz. According to Cáceres Diaz, since the beginning, collaboration has been strong and efficient. Despite the distance, communication has been easy and open which has enabled a firm foundation for a great partnership. “The reason why I like to cooperate with Pemamek is that the company has a big heart. It is easy to work with PEMA people. For Pemamek there are no limits. The future looks promising,“ summarizes Cáceres Diaz.

PEMA VRWP-C, a new generation compact robot solution PEMA VRWP-C, a compact vision robot portal, enables efficient start for robotic welding. PEMA VRWP-C is a robotic solution designed specifically for micro panel welding and it is optimal for flat micro panel stiffeners and T’s up to 500 millimeters (20 inches). Besides shipbuilding, the robotic solution is applicable to other industries as well. Thanks to its compact and modular construction, the smart welding solution is fast to install and commission on site and requires minimum civil work. The solution has a working width of five meters (16 feet), and the length of the working area is expandable in six-meter modules. With PEMA VRWP-C, there exists no need for CAD-files: all welding paths can be processed automatically according to operator’s scanned images of the product and PEMA WeldControl 200 VISION programming software. The solution increases productivity up to 400%, as one robot replaces approximately four manual welders.

LSO process – Highproductivity SAW welding As an ongoing initiative, Pemamek does constant R&D on new efficient welding methods that can be integrated into its automation solutions. One of the new foundings is the long stick-out process, LSO. LSO process is a modern method to increase productivity in submerged arc welding. The LSO process can be used to replace tandem-twin or triple arc processes. The new method is based on a physical principle which, by pre-heating the wire, improves the fusion of the filler metal and increases the deposit rate without changing the welding current or the travel speed. The process is a simple way to increase welding productivity, save time and minimize flux usage and thus decrease welding costs. Pemamek is currently collaborating with Lincoln Electric to utilize the LSO process also for the semi-narrow gap.

Induction preheating enables high speed welding and minimizes angular deformations One of Pemamek’s latest R&D outcomes is induction preheating, a development that optimizes the circumstances for fillet welding. Pemamek’s induction preheating is controlled by an in-house developed software system, PEMA Heat Control. The system calculates the optimal induction power depending on the variables of the workpiece and adjusts the values suitable for induction preheating. Induction preheating is mainly used in MAG and tandem-MAG processes for T-beam and stiffener fillet welding. The panel and the flange are being preheated from underneath to compensate angular deformations. During the welding process of T-beam, induction is also preheating the web on both sides to compensate the longitudinal bending of the T-beam, allowing it to maintain straight. According to Jari Tervolin, PEMA welding engineer, induction preheating enables high speed welding, smooth process, lengthened cooling time of the weld, minimum angular deformations and therefore straight panels and T-beams.



REVOLUTIONIZING NOZZLE WELDING Automated welding of pressure vessel nozzle connections increases the efficiency, reliability, and quality of the end-product.

Optical laser sensor and intelligent software enable high-quality adaptive welding.

The need for welding automation rises as several heavy fabrication industries are trying to combat the shortage of skilled welders. To minimize the effects of welder shortage, companies are required to automize certain processes in their manufacturing or even the entire production chain.

�Data of the scanned groove is processed and presented to the operator in the inhouse developed and easy-to-use software.�

One of the industries that the shortage has hit is pressure vessel manufacturing. The process is demanding, and certain production phases, such as welding nozzle connections, require extremely good welding skills. By automating nozzle welding, the quality and reliability of the nozzle connection welding are raised significantly. This results in a highly improved efficiency of the manufacturing process. When the goal is to modernize the entire pressure vessel production process, Pemamek provides a wide selection of solutions for each phase. In addition to the PEMA Nozzle welding station, PEMA Assembly and Welding stations, roller beds, positioners, and welding columns & booms meet the highest capacity demands of pressure vessel manufacturing.

The basics for efficient automation For the automated and robotized welding to provide maximized benefits, it is required that other processes connected to welding work efficiently and are based on high-quality processes. As an example, it is crucial that weld preparations are at a certain level for automated welding to bring the desired results. The better the preparations are, the more productive welding automation is.

Holes for nozzle connections are recommended to be done with an automated process in order to maintain dimensional changes in the bevel as minimal as possible. Fitting and assembly of the nozzle to the hole needs to be done with care so that the end product will comply with the requirements. PEMA Nozzle welding station with adaptive welding and intelligent PEMA WeldControl 300 SCAN software is designed to overcome the changes in the weld groove caused in the groove preparation or assembly phase. Usually, the nozzle connections are required to be full penetration welds. Manual welding is required for root pass so that high-quality root pass can be achieved. Robotized root pass welding would require very high accuracy in the preparation phase which in most cases is not technically or commercially feasible considering the whole production. After the root pass is manually welded, the robot welds fill and cap passes. Using robot welding for these phases is the most cost-effective solution as the most welding volume is in the fill and cap passes.

Adaptive welding equals high quality and reliability Modern automation and robot welding technology is very adaptive to the variations in the welding groove. The robot adapts to the changes in the groove which enables correct filling and usage of optimized welding parameters. In other words adaptive welding makes it possible for the robot to adjust its movements and control the welding equipment in a manner that will result in successful welding. And successful welding can be done to welds that are not exactly as they are designed in the drawings due to manufacturing or assembly tolerances. Main components that are making adaptive welding possible in the PEMA Nozzle welding station are optical laser sensor and intelligent software. Optical laser sensor is used to measure the weld groove and provide data to the control software. Data of the scanned groove is processed and presented to the operator in the in-house developed and easy-to-use software. By implementing sensors and advanced control softwares welding robots can be raised to the next level of intelligence.

for different materials, consumables and welding preparations. Continuous development is done at the PEMA Process Center where different welding processes for various applications are tested regularly. Additionally, the welding process support with the same welding equipment as in the nozzle welding station can be offered to our customers. Currently, Pemamek’s station is equipped with a single wire GMAW process, but other welding processes, used widely in the process industry, are under development and process test list.

Intelligent programming and control system The core philosophy of welding automation is that it transforms skilled welders to operators who manage the robotic welding station. One of the many responsibilities of the operator is to prepare the upcoming workpiece as the robot is still completing the previous work cycle. When the workpiece is brought inside the robot working area and operators are outside of the robot safety zone, programming of the laser scanning paths is started. With PEMA WeldControl 300 OFFLINE software operator programs the scanning paths to the locations of the nozzle connections with just a few mouse clicks. After the robot has finished an automated scanning work cycle, the data of the scanned groove is presented in PEMA WeldControl 300 SCAN software. The operator can utilize the library of the existing weld pass sequences for the scanned groove or create a new weld pass sequence, which can be saved in the library and applied in the future to similar connections. In the SCAN software, every single weld pass in the sequence is adapted to the scanned groove automatically by the software. Operator can do modifications for the parameters or the weld pass sequence if needed. Fine tuning of the parameters is the point where the special skills and knowledge of the welder are needed. While the robot is welding, programming can be done in either one of OFFLINE or SCAN software. This enables the robot to be utilized more in actual welding rather than path programming or for example online teaching.

For shell diameters up to 3500 mm Pemamek offers two standard-sized solutions for pressure vessels, which dimensions’ cover most of the current market needs. During summer 2020, PEMA Nozzle welding station for shell diameters under 2000 mm, is available for the audience at the Pemamek’s factory. The showcase enables visitors to see more accurately the technical features and advancements of the station. For customers with the heavier and larger diameter workpieces, Pemamek has developed also a bigger standard station that is for up to 3500 mm shell diameters.

Adaptivity of the robot enables correct filling and usage of optimized welding parameters.

After the root pass is manually welded, the robot welds fill and cap passes.

PEMA automation supports Ingalls’s transformation

SHIPYARD OF THE FUTURE As a part of the “Shipyard of the Future” initiative, Ingalls Shipbuilding made extensive investments in modern PEMA shipbuilding automation. As a result, the shipyard’s manufacturing processes have become leaner, more efficient and consistent. Ingalls Shipbuilding, a division of renowned Huntington Ingalls Industries, is an American shipbuilder that has built nearly 70% of the U.S. Navy surface fleet of warships. The shipyard, being in the business for 81 years, has become the largest private manufacturing employer in the state of Mississippi as well as a major contributor to the economic growth of the state of Alabama. Currently, the shipyard covers 800 acres and employs 11,500 people. “Ingalls Shipbuilding is one of the two major shipyards within the corporation. The company is massive and you could easily meet a new person every day. The great thing is that in the company there are a lot of opportunities to grow and develop. I’ve worked here for 15 years now,” tells Kevin Roossinck, Manager of Welding Engineering, Ingalls Shipbuilding. Specializing in military ships, Ingalls Shipbuilding has pioneered the development and production of technologically advanced, highly capable warships. They produce ships for the surface Navy fleet, U.S. Coast Guard, U.S. Marine Corps, as well as foreign and commercial purchasers.

”We wanted to modernize our processes and take advantage of technological developments that had been made in automating high mix, low volume products specifically.”

“We have delivered 31 Arleigh Burke-class destroyers for the U.S. Navy and have now four more under construction. Additionally, we provide the U.S. Navy with San Antonio-class LPDs and have delivered two LHA 6 class ships. A third LHA 6 class ship is currently under construction,” describes Roossinck.

Future of shipbuilding Early 2014 Ingalls launched its extensive “Shipyard of the Future” initiative. The shipyard carefully analyzed shipbuilding needs for the future, how Ingalls matched with those demands and in which the shipyard could improve. Then, the initiative was divided into three areas: people, shipyard facilities, and shipbuilding processes. Roossinck adds, “We wanted to modernize our processes and take advantage of technological developments that had been made in automating high mix, low volume products specifically.”


”Pemamek’s team was able to articulate some of the issues that we had been through with our existing panel line.”

Kevin Roossinck, Manager of Welding Engineering, has worked at Ingalls Shipbuilding for 15 years.

One of the challenges for future shipbuilders is lighter weight materials. The usage of thin panels constantly increases because it provides better performance with lower fuel consumption, faster speed, and agility for the ships. Roossinck continues, “As we have been moving to stronger and thinner steel construction, distortion prevention became a big concern. We wanted to utilize new technology to implement welding processes that would leave us with a finished product significantly flatter and less distorted.“

Leaner, more efficient and consistent

The new thin plate panel line uses the laserhybrid arc welding (LHAW) process combined with tandem MAG, which is capable of welding plates up to 60 ft long and starting from thicknesses as low as 4 mm.

Originally Ingalls had a panel line with mechanized equipment that was better suited for welding thicker materials. Additionally, the one side welding station on the line was not capable of producing full penetration welds from a single side due to joint variation. As a result, Ingalls replaced the one side welding station and added an entirely new production line targeted towards thin panel construction. “Early 2014 we had our first conversation with Pemamek, and right from the start, we were quite impressed. Pemamek’s team was able to articulate some of the issues that we had been through with our existing panel line,” Roossinck continues.

The collaboration started in 2015 when Pemamek won the contract to design and engineer the new panel line. By 2017, Pemamek began its delivery and installation of a state-of-art plate lengthening line, designed to feed two complete modern flat-panel lines simultaneously. The new thin panel line uses the laser-hybrid arc welding (LHAW) process combined with tandem MAG, which is capable of welding plates up to 60 ft and starting from thicknesses as low as 4 mm. “We installed a complete panel line including an automated PEMA hybrid laser one side welding station and two gantries with four robots each. We also replaced our existing SAWOSW with a new integrated PEMA milling OSW.” In the LHAW panel line, one of the advanced features is a fully automated robotized welding station for entire panel stiffening. The solution includes multiple robots utilizing Pemamek’s hi-tech programming and control software, PEMA WeldControl 200. In 2018 Ingalls decided to invest in additional PEMA shipbuilding automation and the PEMA Bulkhead production line was ordered. The solution consists of integrated milling and laser-hybrid one-sided welding station, profile and T-beam assembling and tack-welding solutions, as well as two robotized welding portals both of which include two robots and special conveyor solutions. The automation solutions will be installed and commissioned in late 2020. Roossinck continues, “The result of PEMA solutions has been a significant improvement in performance from a distortion standpoint and improved consistencies of individual processes within the production flow. We have become leaner, more efficient and more consistent with the quality and flow of our panels through the shop.” At Ingalls Shipbuilding the PEMA automation lines have resulted in a raised level of automation, enhanced production quality, and improved workflow.


The trust factor By acquiring modern production automation technology, Ingalls transformed a lot of its manufacturing processes. Production phases that used to be done manually are now done by the machine. As a result, welders who before were doing the manual work are now operating the large machines. According to Roossinck, a successful adaption requires “on-the-job” training and support from the supplier, but also employees need to learn to trust the technology.

”As much as 68% better than the shipyard’s baseline performance.”

“We had to learn to become more computer-based and rely on technology and models to do most of the work for us. There is a trust factor there and it takes some time for employees who are used to doing everything by hand themselves to turn most of the labor over to a computer or machine,” Roossinck remarked. To help smooth the transition from manual labor to automation, Roossinck emphasizes early and open communication between suppliers and the customer’s production team. Roossinck adds, “Communication upfront with the production team is important to prepare them for how PEMA equipment is going to change the way they do their job.”

In the LHAW panel line, one of the advanced features is a fully automated robotized welding station for entire panel stiffening.

Efficiency from start to finish At Ingalls Shipbuilding the PEMA automation lines have resulted in a raised level of automation, enhanced production quality, and improved workflow. “The line allows us to split our panel production between thick and thin material, which has streamlined the flow of panels through the shop. The overall production is much faster because we have more than doubled our capability to build panels by adding a line of equipment that is more efficient than the existing production line it compliments, “ Roossinck tells. As a result of the modern welding automation and streamlined production, Ingalls has noticed significant improvements in the distortion data, as much as 68% better than the shipyard’s baseline performance. “The PEMA equipment has helped us break through where we thought the bottlenecks would be and the result is a more efficient line from start to finish. We have fundamentally changed the order in which we produce panels. Pemamek’s flexibility and customization of equipment allowed us to do that,” summarizes Roossinck.

“We had to learn to become more computerbased and rely on technology and models to do most of the work for us.”-Kevin Roossinck, Manager of Welding Engineering, Ingalls Shipbuilding

Increase efficiency in trailer frame welding.

PEMA Robotic welding station with PEMA WeldControl 300 OFFLINE programming.

High production capacity, optimized workflow, and improved factory layout.

Transportation equipment manufacturer VAK invested in PEMA robotic welding solutions. The investment brought significant benefits throughout the process. VAK Oy is a Finnish family-owned business and specializes in providing transport equipment solutions for the Northern European highways. Located in the Southwest of Finland, the company employs over 500 people and has a subsidiary in Sweden. As a growing and future-oriented company, VAK constantly fine-tunes its operation methods and processes. “In our operations, the guiding factor is high-quality products. In addition to the quality of products, we also focus on developing the quality of operations and procurements,” describes VAK’s Sales director and Board member, Matti Virtanen. As one of the main manufacturers of transportation equipment for the Nordic countries, VAK provides a wide selection of heavy-duty structures for the industry. “We design and manufacture structures, such as trailers, cargo compartments, and demountable bodies for the transportation industry,” describes Virtanen.

From manual welding to robotized For VAK, one of the biggest product groups is trailer frames. The yearly volume is around 500. The size of one frame can be as much as 17,5 meters long and 2,5 meters wide. A few years ago, the assembly welding of the trailer frames was done completely manually. As the incoming orders started to gradually grow and advanced manufacturing technologies to evolve, VAK decided that it was time to invest in a better capacity and more efficient production flow. “The assembly welding was before done manually and this was one of the phases that we saw an opportunity for optimization.” Virtanen continues, “The main reasons why we started to consider automatized robotic welding was to improve process efficiency and above all to invest in our future capacity,” comments Virtanen. To optimize the assembly welding of trailer frames, VAK ordered a comprehensive PEMA robotic welding station. The robotic welding station included XYZ- gantry, one welding robot, and two headstock positioners with two manually adjustable supporting units. As a programming method, the station uses PEMA WeldControl 300 OFFLINE software.

Benefits throughout the process The station was delivered in 2018 and ever since VAK has been able to enjoy the benefits from robotic welding. “The production goals that we set for the robotic welding station, have been accomplished and our production is now significantly more efficient. The station has brought several benefits to us,” said Virtanen. VAK acquired PEMA Robotic welding station to boost trailer frame welding. The station, with PEMA WeldControl 300 OFFLINE, has made the production significantly more efficient.


In addition to improved welding efficiency, the benefits are visible in other production phases as well. After implementing welding automation, VAK has gotten a better understanding of their trailer frame production and increase predictability. “Throughput, planning, and scheduling of our production are working now a lot better. Automated welding requires the designing to pay more attention to details, so our 3D models have also improved. Additionally, we’ve been able to develop our product modularity,” lists Virtanen. Thanks to the robotic welding station, the factory layout has improved as well. Virtanen comments, “The existing square meters in the factory were optimized at the same time and now all the space is in better use.”

Key to successful start-up At VAK, the ramp-up and adaptation phases went well and production was started efficiently. Some of the main factors for a good implementation Virtanen mentions early and all-rounded training.

“The production goals that we set for the robotic welding station, have been accomplished and our production is now significantly more efficient. The station has brought several benefits to us.”

“If the personnel is well trained for the new methodologies, the ramp-up time is significantly faster. Together with Pemamek’s support, our motivated and fastlearning production team was able to pick up the new welding technologies quickly,” says Virtanen. Positive experiences as a foundation, the company does see the role of welding automation to grow and at some point is ready to harness further automation in its production. “We are very happy with our collaboration with Pemamek. It was easy to reach Pemamek and the team actively and genuinely wanted to help us. Automation does bring benefits and we think that in the future we will also acquire more when time is right,” summarizes Virtanen.

As a programming method, the station uses PEMA WeldControl 300 OFFLINE software.

Complete solution to weld dumper bodies Istrail’s yearly volume of dumper bodies is around 500. The size of a typical dumper is up to 10 meters long and 2,75 meters wide. One dumper can weigh as much as 8 tons. “We manufacture very large and heavy structures. The PEMA Robotic welding station makes it more efficient and safer to manufacture heavy and dimensionally large dumpers,” Skipenes describes. The delivered PEMA Robot welding station with Single MAG welding process included the XYZ floor track gantry system, two production cells that both have PEMA Headstock and a manually adjustable support unit. The robot is programmed with PEMA WeldControl 300 OFFLINE. The two cells are operated with CellControl 700 which enables an unmanned production with the robotic system. According to Skipenes, one of the main factors impacting Istrail’s decision to invest in PEMA Robotic solution were turn-key delivery and modern programming system, “We did a study and it turned out that Pemamek’s offline programming tool was the most userfriendly software to use. Additionally, for us, it was important to get all services from designing to production support from one supplier. These were a few of the reasons why we selected Pemamek.”

Fast adaptation, significant benefits Since Istrail did not have much previous experience in robotic welding, the company was not sure how the start of the production would go and how fast the start-up would be. “When acquiring new technology, you cannot be fully sure how the implementation goes and how the production team adapts the new technology to their routines. For us, it came as a positive surprise on how fast we were able to start with the station. We received extremely good support from Pemamek, which has very creative and solution-oriented professionals.” The PEMA Robotic welding station has been in full production for five years now. Istrail has been able to increase its production output and improve welding quality but also noticed improvements in the working environment. “The robotic station has made our heavy-duty production a lot more efficient. Also, it has improved our environment in the factory, such as decreased smoke and loud noises, and of course, improved overall working ergonomics,” describes Skipenes.

”The robotic station has made our heavyduty production a lot more efficient.”

New robot station delivery in 2020

The PEMA robotic welding station has made Istrail’s heavy-duty production a lot more efficient.

When asked about the future and role of welding automation, Skipenes thinks that the steel industry is gearing up for automation, and Istrail, based on their previous experiences, follows that trend. Skipenes comments, “Automation makes the job easier - also for the welders. This is why I believe that the role of the welding automation grows.” Istrail has already set its eyes on the future and plans to increase the level of automation in its factory one step at a time. The second robotic welding solution is already in the pipeline. “Our next PEMA Robotic welding station, which will be delivered in spring 2020, will be a bit bigger than the one we have now. The station brings us significant advantages and enables us to expand even more the variety of our largest heavy steel constructions. We are really looking forward to that,” summarizes Skipenes.
